Metal Roofing in Huntington, New York — Lifetime Interlock® Aluminum Shingles Installed Locally

Yes—aluminum's oxide layer actually strengthens when exposed to freeze-thaw stress, rather than degrading like asphalt or wood. Huntington averages about 66 freeze-thaw days per year, and Interlock's 3105-H24 aluminum alloy (ASTM B209 certified) has been installed successfully in climates with similar or harsher cycling for over 25 years. The four-way interlocking panels also allow for thermal expansion without cracking, and because the material weighs only 0.41–0.59 lb/sq ft, ice load doesn't create structural strain that can lead to failure.

Huntington's roughly 63 cm of annual snow slides off aluminum panels cleanly rather than compacting into ice dams, because the smooth surface and thermal properties prevent melt-refreeze cycles. The lightweight design—your new roof adds virtually no snow load stress compared to slate or concrete tile—means existing rafters handle the weight easily. Optional snow guards are available if you want to manage discharge. The real advantage: no interior water damage from backed-up ice the way asphalt shingles fail under repeated freeze-thaw with 1,251 mm of annual rainfall.

Four-way interlocking panels create overlapped, mechanical seals on all four sides—water cannot reach substrate or decking the way it penetrates overlapped shingle tabs. With Huntington receiving about 1,251 mm of rain annually over roughly 66 freeze-thaw days, asphalt shingles curl, split, and expose fasteners; aluminum never splits or curls. Paired with solid-deck installation and underlayment (same as code-compliant asphalt), Interlock roofs over Huntington since 2014 report zero leak callbacks. The ICC-ES ESR-1790 evaluation confirms drainage and water-tightness under the IBC/IRC standards your town enforces.

Aluminum cannot rust because it contains no iron—rust requires iron. Instead, aluminum develops a microscopically thin oxide layer that blocks further corrosion; when scratched, this layer self-heals chemically. Steel roofing, by contrast, must be coated to prevent rust, and coatings fail over time. Interlock's Alunar 70% PVDF fluorocarbon finish (applied to both sides) extends the protection with a 30-year warranty against chalking and fading. In salt-air coastal environments and harsh industrial zones, aluminum's immunity to rust is why it's the only practical choice—Interlock panels have been installed from coastal homes to Antarctica.

Yes. Huntington experiences typical gusts reaching 135 km/h, and the four-way interlocking design resists wind speeds up to 120 mph (193 km/h) when installed to specification—that's a safety margin well above local conditions. The mechanical interlock on all four panel edges creates a unified structure rather than relying on nails and adhesive alone. Interlock's ICC-ES ESR-1790 evaluation certifies this under IBC/IRC wind-load testing. In 11 years of service by your local installer, high-wind events have not resulted in uplift or panel separation failures.

Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the warranty covers perforation from hailstones up to 1.5 inches. Class 4 impact resistance is rare; most asphalt and even some metal roofs only reach Class 1 or 2. Many homeowners find that this rating qualifies them for insurance premium discounts; contact your agent with the UL 2218 certification. At Huntington's latitude, hail is less frequent than in inland climates, but when it occurs, Class 4 protection means no cosmetic denting claims and no interior damage.

Yes. Interlock's Mediterranean Tile profile weighs roughly 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so most existing Huntington homes need zero structural reinforcement. Even the heaviest Interlock profile (Shake at 0.58 lb/sq ft) is negligible compared to the dead load your rafters already carry. This means you can often avoid the cost and mess of a full tear-off; the new roof installs over asphalt shingles, which your local Interlock installer has done since 2014. A structural engineer will confirm if your home qualifies, but the lightweight aluminum design makes retrofit feasible for nearly every residence.

The Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance with zero degradation clauses. When you sell, the warranty transfers to the next owner for 50 years from completion. Interlock has been manufactured since 1998 (26+ years of field data), and panels installed at the company's earliest sites in coastal and freeze-thaw climates still perform. The 30-year Alunar coating warranty and Class 4 hail rating ensure no premature failure modes. It's the last roof you'll buy.

Aluminum requires virtually no maintenance—no algae removal, no shingle replacement, no gutter debris from decomposing material. Asphalt shingles fail after 15–20 years and shed granules into gutters; wood shakes split and rot in Huntington's 66 annual freeze-thaw days; concrete tile cracks and traps moisture. Interlock is CALGreen-verified for reduced maintenance. A yearly gutter cleaning (standard for any roof) is all you'll do. The Alunar fluorocarbon coating resists UV degradation for 30 years, so there's no need for re-coating or sealant refresh like metal roofs without premium finishes.

Yes. energy-efficient Interlock colors have initial solar reflectance up to 0.55 and thermal emissivity of 0.84, meaning they reflect heat that asphalt absorbs and radiates into your attic. Over Huntington's roughly 3,115 annual sunshine hours, this reflectance reduces air-conditioning load, especially on south and west-facing roofs. The Cool Roof Rating Council certification confirms measurable energy savings. Savings vary by roof pitch, orientation, and HVAC efficiency, but metal roofing typically reduces summer cooling by 10–15% compared to dark asphalt. The white or light-colored profiles deliver the greatest benefit.
